Abstract (en)
[origin: WO2014075852A1] The invention relates to a method for operating a drive unit for a hybrid vehicle, wherein the drive unit comprises a drive assembly (3) with an internal combustion engine (1) and an electrical machine (2) and a transmission (5) having a plurality of gearboxes (6, 7) connected between the drive assembly (3) and an output (4). The electrical machine (2) is coupled via a planetary gear unit (10) to an input shaft (8) of a first gearbox (6) and an input shaft (9) of a second gearbox (7) connected in parallel with said first gearbox (6). The internal combustion engine (1) can be coupled by means of a friction-fitting decoupler (11) to the input shaft (8) of the first gearbox (6) and when the decoupler (11) is closed is coupled together with the input shaft (8) of the first gearbox (6) to the same element (15) of the planetary gear unit (10), To couple the internal combustion engine (1) to the output (4) from travel under solely electrical power, the torque provided by the internal combustion engine (1) is transferred via the decoupler (11) operated in slipping mode, so that a shifting element previously closed during solely electrical operation is relieved and to disengaged in the relieved state.
